Bundgaard Reaches High Environmental Standards by Utilizing Hydrocarbon Optimized Products from Danfoss

15 September 2011 | Author: Asbjørn Leth Vonsild, R&D Business Development
R290 propane-based cooling systems, chillers and heat pumps require high performance components. When Danish manufacturer Bundgaard looked for a quality supplier for these safe and efficient systems, they looked to Danfoss.

Chapter 1. Bundgaard
With more than 50 years’ experience in the cooling industry, Bundgaard has a longstanding reputation
for quality. But that’s not the only priority for the company, which is rapidly becoming a leader in Denmark for R290 propane-based hydrocarbon cooling systems.

The natural refrigerant R290 propane has particularly efficient thermodynamic properties. Bundgaard
produces up to 50 state-of-the-art hydrocarbon systems each year, and the industry segment continues to grow. However, the flammable gas also requires detailed safety measures.

“At Bundgaard, our first concern is safety, and we design our systems to withstand the worst-case scenario,” says company sales and marketing representative Morten Sminge Frederiksen. “Our products have to be safe and easy to work with for our customers, mounters, colleagues and our partners in business.” Safe products require reliable, quality components – one of the many reasons why Bundgaard chooses Danfoss. Utilising Danfoss coils, filters, EVRE solenoid valves and KP-E pressure controls especially developed for hydrocarbons, Bundgaard’s R290 propane systems are not only reliable – they also help to significantly lower customers’ operating and maintenance costs.
Chapter 2. A More Efficient System

With R290 models such as the A/W Chiller, A/W Chiller V-condenser, W/W Chiller, and W/W Heat Pump, Bundgaard systems have diverse and customisable applications, from comfort cooling in large offices and production plants, to swimming pools, stables and farms.

“We’re very aware that in these industries, efficiency is paramount – both for our customers’ operating
costs and for the environment,” says Frederiksen. “As a company, our focus is to produce safe, energy-saving products with low environmental impact, and Danfoss components are an important part of that process.”

With the R290 propane refrigerant in cooling systems, chillers and heat pumps, Bundgaard achieves
significantly more efficient results for their customers. And the R290 propane systems are among the most environmentally friendly systems on the market.

An important measure for the environmental impact of a refrigerant is the Global Warming Potential (GWP), which quantifies the global warming potential relative to CO2. To illustrate the environmental advantage of the R290 systems, the GWP of the refrigerant HFC R410A is 1720 compared to just 3 for R290 (TEAP). That means that 1 kg of R410A has the same potential to impact global warming as 1720 kg of CO2, where 1 kg of R290 is equivalent to only 3 kg of CO2. This equates to a huge reduction of GWP for Bundgaard customers – a fact that the company takes pride in.

Future legislation will most likely increase the focus on more efficient and environmentally sustainable
cooling systems and, along with Danfoss components, Bundgaard is at the forefront of this rapidly growing technology.
Chapter 3. Lower Charge, Higher Expectations

The R290 systems require an extremely low charge in the unit, comparatively, and the rest of the cooling system uses water. This both increases safety and gives a low environmental impact from the refrigerant.

“It’s such an efficient process,” says Frederiksen, “that some Bundgaard clients have a hard time believing it.

“A customer called us and said, ‘The system must be broken, it uses too little power.’ Of course, there was nothing wrong with the system, but the low energy consumption had confused their external monitoring equipment.” It was bound to be misread, Frederiksen explains: their monitoring equipment was set up for an HFC system.

The high performance of an R290 system requires Danfoss quality components for safety, performance and reliability.

“Danfoss has a great reputation,” Frederiksen notes. “We put a high priority on quality and performance – which Danfoss lives up to – but we also choose them for their service and competitive pricing. Danfoss’ fast technical support and flexible delivery mean that we can focus on our customers. That creates great relationships all around.”

Danfoss - Your Hydrocarbon Solutions Provider

Danfoss considers hydrocarbons among the most attractive refrigerants in display cabinets, bottle coolers, heatpumps, chillers. This is because  hydrocarbons have zero Ozone Depleting Potential (ODP), extremely low Global Warming Potential (GWP), and systems with these refrigerants are very efficient in a wide range of conditions.
